Preventative Maintenance The printed circuit boards of the analog modules must be protected
from dirt, oil, moisture and other airborne contaminants. To protect
these boards, install the SLC 500 system in an enclosure suitable for its
operating environment. Keep the interior of the enclosure clean, and
whenever possible, keep the enclosure door closed.
Regularly inspect your terminal connections for tightness. Loose
connections may cause a malfunction in the SLC 500 system or
damage the components of the system.
For general maintenance procedures for electrical equipment, refer to
the requirements specific to your region.
